The value of rose bengal plate test (RBPT) in diagnosing brucellosis in cattle was determined by statistical comparison of its results with the results of the tests used in Poland, i.e. SAT, CFT, AGT and MET. RBPT was made in 2 variants. In routine, highly specific test, equal parts of antigen and serum--0.03 cm3, were used whereas in the experimental one the sensitivity was increased using half the amount of antigen--0.015 cm3 (RBPT0.015). Two batches of cattle serum were examined. In group I 249 cattle serums from the herds infected with brucellosis were examined. In group 2 there were 1269 cattle serums from the herds free of brucellosis, positive in SAT but negative in CFT. The reactions in SAT were considered as not specific if the reaction in the additional examination in CFT, AGT and MET was negative. On the basis of the results in group I, mainly the sensitivity of RBPT was determined compared with the total evaluation of the results of SAT/CFT. In RBPT0.015 the consistency of the results was 99.4% but in RBPT0.03 only 87.9%. Detectability of reactions, i.e. the percentage of positive results in infected herds was calculated. The results were as follows: AGT--89.6%, RBPT0.015--74.3%, SAT/CFT--66.3%, CFT--65.9%, RBPT0.03--59.8%, SAT--55.4%. In the group 2 mainly specificity of RBPT in relation to CFT, AGT and MET was determined. In RBPT0.03 it achieved 97.1% whereas in RBPT0.015--83.1%. The application of RBPT0.03 in the group 2 eliminated 95.8% of the not specific reactions in SAT and that of RBPT0.015--77.9%, respectively. The author suggests to use RBPT0.03 as a screening method instead of SAT and CFT to diagnose cattle brucellosis in the areas free from the disease. On the other hand, RBPT0.015, as more sensitive test is suggested to be used in the herds suspected of brucellosis to identify quickly infected animals.

Serological activity of swine IgM and IgG against Brucella abortus in RBPT was determined in relation to four other reactions used in Poland for diagnosing brucellosis standard agglutination test, complement fixation test, antiglobulin test, 2-mercaptoethanol test). Isolation of IgG was performed by the method of filtration on Sephadex gel G-200 of swine sera raised against Brucella abortus S19 by double immunization with suspension of killed bacteria. The presence of a certain Ig class in the fractions thus obtained was confirmed by immunoelectrophoresis and immunodiffusion tests. RBPT revealed the reaction of antibodies of IgM and IgG class which proves usability of this reaction diagnosis both early (IgM) and chronic (IgG) infection with brucellosis. Both classes of antibodies mentioned above were active also in SAT and CTT. Also the results obtained in AGT and MET were found interesting. In one of the sera, the absence of incomplete antibodies was observed, whereas positive reaction in antiglobulin test was found in its fractions containing IgG. This phenomenon was determined as concealment of incomplete agglutinins through higher level of complete antibodies in normal serum. In swine (the results were different from those obtained for cattle), apart from incomplete antibodies in IgG class, the presence of these agglutinins in IgM class was noted. On the other hand, the results obtained in MET proved that IgM antibodies of swine were not totally reduced when affected by 2-mercaptoethanol.

In the examinations of the swine sera obtained from swines immunized s.c. with adjuvant Br.abortus S19 vaccine or Br.suis 1417 vaccine, it was found that agglutinins were present after 3 weeks, and C.F. antibodies or incomplete agglutinins normally after injections. Probably, in the first period of Brucella infection negative results of C.F.T. or AGT or both will be obtained. In the swine sera from Brucella free herds, agglutinins reacting with the Brucellognost antigen were present. The performance of mercaptoethanol test or C.F.T. lead in most cases to suitable diagnosis. In our conditions we have not obtained results which permit to classify AGT as a supplement test in serodiagnosis of swine brucellosis.

The distribution of different genotypes of Yersinia enterocolitica strains recovered from humans and from healthy pigs was investigated using PCR fingerprinting. The thirty six strains of Y. enterocolitica from humans, thirty five strains from pigs and Y. enterocolitica ATCC 9610 strain were included in this study. The tested strains of Y. enterocolitica belonged to O3 and O9 serogroups. The PCR fingerprinting using EAE5 primer (5' CTT AAT CTC AGT AAT GCT GGC CTT GG) made it possible to form five groups among the tested Y. enterocolitica strains. Two groups were very numerously represented by the tested strains. The thirty of Y. enterocolitica O3 strains from humans (thirty one of tested) and eighteen of Y. enterocolitica O3 strains from pigs (twenty of tested) belonged to one group. This group also included Y. enterocolitica ATCC9610 strain and four Y. enterocolitica O9 strains from pigs. All investigated Y. enterocolitica O9 strains from humans and the majority of Y. enterocolitica O9 strains isolated from pigs created a second, numerous group. The third genotype was created by two strains O9 from pigs, and the remaining two strains, isolated from pigs, belonging to O3 and O9 serogroups showed different binding patterns revealed by gel electrophoresis and created two other genotypes. The tested Y. enterocolitica strains which were isolated from humans formed only two groups but Y. enterocolitica strains isolated from pigs were found in five groups but such as the Y. enterocolitica strains from humans, the majority of strains from pigs were in first and second group. The Y. enterocolitica O3 strains regardless of their origin mostly represented the same PCR fingerprinting profile. The tested Y. enterocolitica O9 strains were more genetically diverse and represented four PCR fingerprinting profiles.
